Safety film is now mandatory in many countries for racing and rallying. It's easy to install and will prevent the thousands of pieces of shattered glass filling the car with debris and dust, should you have a mishap. In many cases the window can be removed in one piece and disposed of. Many drivers in closed cockpit cars don't wear any eye protection and a wall of glass filling your helmet at speed could turn a glancing blow and a simple broken window into an avoidable disaster. This film provides 25% UV protection and 86% heat reflection. The roll of film measures 51cm x 4 metres, with a thickness of 100 microns. This film fully complies with FIA requirements.
